This commit makes sure to respect the MBeanServer#invoke contract by
wrapping any user-defined exception in an MBeanException. Also, any
exception not from the JDK is translated, as it may lead to unexpected
issue on the client if that class isn't present. This is consistent
with our operation result mapping strategy.

This commit also updates tests since UNDERTOW-1260 has been fixed in

As pointed out by Rossen in gh-11514 comments, a handler might commit
the response and then send an error signal in the pipeline. In this
case, adding a callback to `beforeCommit` is useless because it won't be
triggered. In those cases, we need to collect metrics right away.
